Rochester Quadrajet Woes
Has multiple issues. Check for spark and plug condition. On that style carb choke thermostat is heated by the intake. There should be a operating heat riser. Most times on older vehicles there is some restriction to the crossover passage or stuck heat riser. Those need to be checked at some...- fast 99

1988 Suburban Door Locks
Simple powered circuit not through ECM. Check for power when solenoid in energized. If not present go upstream until there is power. Should also be power on the switch. Will work with key off. -
Help identify strange noise at Highway speed
Does anything change when put in neutral? A hole in the floor will amplify any noise. Is it possible to capture the noise on a video. What you describe is unusual.- fast 99

Let’s slay this dragon…
Any wire with a crimp on connector is not factory, such as the yellow wire near the flasher. Not saying that is all bad just trace it down. If not deleted make sure whatever it is powering doesn't overload that circuit.- fast 99

Oil Pressure Drops After High RPM
Have seen Lucas at local stores. Another place to check is Walmart. OP when you drain the 5-30 out take a stick or screwdriver and swirl the oil around in the drain pan. If it looks at all like metal flake paint quit right there, bearings are in the pan.- fast 99

Were on the same page. Actually, most 5-30 oils shouldn't be used with flat tappet cams, additive package is wrong.- fast 99

Oil Pressure Drops After High RPM
Change to a thicker oil 10-30 or 10-40. If it continues need to confirm with mechanical gauge. If indeed pressure is that low how old is the engine? Could have a restriction, possible pickup plugged with crud or RTV? Could also be holding the oil on top if drain back holes are restricted. Other...- fast 99

LMC Dash Pad Supplier
I purchased a pad, from Jegs. Was double boxed with a Dashes direct part inside. Shipping was either free or substantially less than most other places. Also took that route with a bed floor. -
350 tbi running too cold
Also keep in mind where the sender is. If in head it will read about 10 degrees hotter than near the stat in the intake. Really cheap to diagnose and a very handy tool to have. Go to HF and buy a temperature gun. Run vehicle a while, check stat housing. When I bought mine it was $250 now HF...- fast 99

A/C Question
It's not difficult but some procedures need to be followed. Any part not replaced needs to be flushed of oil and contaminates. In addition to previous post replace all lines and seals. Buy a conversion kit. Replace hoses if original, they are too old, 134A is a smaller molecule will leak easier...- fast 99

First real drive! Not tragic but not good. I think I need carb advice.
A couple pictures would help. Obviously with headers the heat riser valve is gone. That effects intake preheat and choke operation. Hard to help with diagnosis not knowing what your working with.- fast 99

Weird leak..
Have seen coolant leaks that only occur when vehicle is cold, especially plastic tank radiators. Holding pressure for long periods shouldn't be a problem as long as it isn't excessively high.- fast 99

First real drive! Not tragic but not good. I think I need carb advice.
Before thinking about buying parts some diagnosis first. Check over the tune up, good plugs not fouled, timing, both advances, inspect wires, cap, ect. Check fuel pressure and volume. If possible check vacuum. If it does have a q jet with appreciable age likely float is heavy and needs o haul...- fast 99

Engine Block Heater for SBC 350
Good battery means adequate amperage to crank fast enough in a cold environment. Shouldn't be using heavy grade oil 10-30 or 10-40 ok, no 20-50. To remove a freeze plug, use a blunt punch of some kind or even a long 1/2" extension. Hit it towards the outside edge. It may twist in the hole...- fast 99

Engine Block Heater for SBC 350
Most reliable and easiest to install are soft plug heaters. Directions will instruct which one to install it in. Remember GM installed them from the factory. I live in Spokane, we get comparable weather. Actually any maintained vehicle with a good battery should start decent in 0 degree...- fast 99

Brought home my first square body. 1980 Silverado C10. Utah
Am sure the shows will continue somewhere else. Broadcast media is dying a slow death. 10 years from now may not be any left. I am on cable basically because most of what I watched used to be in one place. Now its horribly expensive with less content. That is unless you like watching drug...- fast 99
